However, researches on its nutrition and economic values are scarce leading to low production and under consumption among the populace. Against the backdrop of the great potential of the Nigerian agriculture in cocoyam production, and the need for land use efficiency, sustainable development, poverty alleviation, attainment of food –security/ self-sufficiency and adequate resource allocation to the production of the crop, this study examined farm level profit efficiency and its determinants for smallholder cocoyam-based farmers in Osun State, South-west Nigeria, using Cobb-Douglas stochastic profit function. Multistage and random sampling techniques were used to select 180 small-holder cocoyam farmers during the 2014 growing season and data were collected from them on their socio-economic and production characteristics. Maximum likelihood estimates of the specified models revealed an average profit efficiency of 44.88 percent which indicated that the profit of the farmers can be increased by 55 percent with the same production cost. The study also found that the level of education of the farmers, access to credit, farming experience, household size, access to extension services, and marital status are factors affecting farm-level profit efficiency in the use of resources. Farm-level policies aimed at promoting the farmers education, access to credit, access to extension services and marital status are recommended for improved profit efficiency. \u0000 \u0000 \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115087528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water scarcity is one of the major challenges affecting the livelihood of people in Kazaure town. The aim of the study was to examine water scarcity at micro level, in Kazaure town. A total of 1520 samples were selected which constituted 0.4% of the total population. The respondents were selected using availability sampling at water collection points of which only 1500 questionnaires were successfully returned and 20 were not. The data was analysed using simple descriptive statistics and Analysis of Variance (ANOVA) single factor. Results revealed that 20% of the sampled population has resorted to land leasing near water sources for their farming activities, 53% has stopped dry season farming in the area of fishing, 45% of the sample respondents have stopped fishing while 56.5% indicated that they have resorted to providing their water needs by themselves. The study revealed that there are only 60 hand pump boreholes in the whole of Kazaure. The ANOVA test also indicated that there were no significant differences in terms of water sources between the settlements at 0.05 level (P 0.067) and there were significant differences in terms of water facility types between the settlements at 0.05 level of significance (P 0.046). It was established from the study that water scarcity has negatively affected livelihood activities in the study area. The paper recommends that private sectors should be encouraged to pool resources together to provide and improve water supply projects and state and local government should provide more mechanical powered bore holes in the areas for effective water supply. \u0000 \u0000 \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116564217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three isonitrogenious and isocaloric diets containing between 20.5 to 21.1 % CP and 3440 to 3454 kcal/kg ME were formulated. The control diet contained none of the animal protein sources while the other two diets contained blood meal and fish meal at 6%, respectively. After six weeks of straight feeding, data were collected on feed intake, weight gain and feed conversion ratio was calculated. Carcass characteristics and cost benefit were also calculated. The results indicated that birds fed fish meal based diet consumed more feed (p< 0.05) than those on control diet, while intake of those on blood meal based diet was an interphase between the control and fish meal based diet groups. The birds fed fish meal based diet also recorded higher (p< 0.05) daily weight gain than those on control and blood meal based diets. Feed conversion ratio was better in the group fed fish meal based diet than those fed the control diet, but similar (p> 0.05) to the group fed the blood meal based diet. The dressing percentage of the birds was similar (p>0.05) in the control and blood meal based diet groups, but they were higher (p<0.05) than the fish meal based diet group. The neck, back, drumstick and head were significantly (p<0.05) higher in the control group than in the groups containing animal protein. Cost benefit analysis showed that feed cost and cost per kg weight gain were higher (p< 0.05) in fish meal based diet group than in control and blood meal based diet groups. Revenue per bird and gross margin were higher (p< 0.05) in the blood meal based diet group than in the control diet and fish meal based diet groups.

There is the need to determine the best type of cutting and growing medium protocols for commercial production of this species. Seven homogenous growing media (sawdust, topsoil, charcoal, coconut husk, wood shavings, maize cobs and rice husk) and two types of cutting (apical and non-apical) were compared in a factorial experiment laid out in Completely Randomized Design with six replications at the Federal University of Agriculture, Abeokuta, Nigeria between 2010 and 2012. Data collected on plant height, number of leaves, leaf area, shoot dry weight, days to spiking, length and number of spike, size and number of florets were subjected to analysis of variance and Tukey’s HSD at p ≤ 0.05 to separate treatment means. Apical cuttings were significantly (p ≤ 0.05) superior to non-apical cuttings in terms of all parameters assessed except floret diameter which was statistically similar. For growing medium, dry matter accumulation and spike yield were in the order of charcoal > rice husk > maize cob > topsoil > wood shavings > coconut husk. Apical cuttings planted in charcoal or rice husk gave the best results relative to other media. Thus, apical cutting is the best propagating technique and charcoal or rice husk is the best growing medium for scorpion orchid cultivation. \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"237-240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130731173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
